The much-anticipated results of the stress tests of Europe's banks will be published after the markets close on Friday, the Committee of European Banking Supervisors (CEBS) said today.

The markets are keen to learn how the 91 banks which have been subjected to the tests have performed and could be volatile in the run up to the results.

CEBS said it will publish aggregated results in the form of a summary report and main conclusions on its website at 1600 GMT – 5pm local time in the UK. At the same time, the banks and their national supervisors will publish individual results on their own websites. About half an hour later, CEBS added, a summary of the 91 bank-by-bank results will be available on the CEBS website.

Four UK banks – HBSC, Barclays, Royal Bank of Scotland and Lloyds Banking Group – are among the institutions that have been subjected to close scrutiny of their balance sheets to establish if they have enough capital to withstand an economic downturn alongside a sovereign debt crisis.

In testing 91 banks, Europe is measuring the health of 65% of its banking sector in an attempt to give the assessment as much credibility as possible.

Spain's cajas (savings banks), Germany's Landesbanks (regional banks) and Greek banks are regarded as those most likely to need fresh injections of funds.

At Barclays Capital, analysts estimate that the cajas may need €36bn, Landesbanks €34bn and Greek banks €8.6bn, either because of their holdings of debt issued by European countries or because of the losses they have suffered on property loans.

The Greek banks could raise any fresh funds through the markets such as rights issues on their shareholders, while the German and Spanish banks might need help from the funds that their governments have set up to recapitalise their respective banking sectors.
